Memory for objects and places following lesions of the hippocampus or perirhinal cortex in rats
… either bilateral aspiration lesions of the perirhinal cortex or bilateral NMDA lesions of the hippocampus. Rats learned three different object discrimination problems: They learned one problem approximately 72 hours prior to surgery, another problem approximately 24 hours prior to surgery, …

Hippocampal output to neocortex: Examination of the electrophysiological and plastic properties of CA1 projections to the perirhinal cortex
… long-term storage is believed to occur in the neocortex and the physiological mechanism underpinning this transfer of information is believed to be long-term changes in synaptic plasticity, namely long-term potentiation (LTP) and depression (LTD). The aim of this thesis is to characterise synaptic …

Functional dissociation between the hippocampal formation and perirhinal cortex : evidence for independent memory systems in the medial temporal lobe
… that the hippocampal formation (HPC) and the perirhinal cortex (PRh) are serial components in a unitary memory system. Contradictory to this view, evidence from numerous studies with monkeys and rats suggest that there are at least two independent memory systems within the medial temporal …

HORROR-EVOKED AROUSAL AND AMYGDALA BIAS OF THE MEDIAL TEMPORAL LOBE
… the anterior and posterior hippocampus, and the perirhinal cortex. We present neural univariate signals of these regions of interest (ROIs), and functional connectivity between ROIs (basolateral and central-medial amygdala, anterior and posterior hippocampus, perirhinal cortex) to see successful …

Cognitive neuroscience methodologies provide insight into medial temporal lobe contributions to perception, language, and creativity
… of medial temporal lobe sub-regions, namely perirhinal cortex and hippocampus, to a variety of capacities classically considered outside the domain of memory. Several studies are presented that demonstrate the contribution of these regions to certain aspects of perception, language, and …

Content representation in the human medial temporal lobe
… distinct subregions including hippocampus, perirhinal cortex (PRC) and parahippocampal cortex (PHC). However, the computations performed by each subregion to encode individual events is still unclear. The present research tests the central hypothesis that different forms of event content are …

Pattern Separation in the Ventral Visual Stream
… the top of the VVS object processing hierarchy, Perirhinal Cortex (PRC). During scanning we presented images of objects from multiple categories, with differing degrees of visual similarity among exemplars during performance of an N-Back task. Imaging results obtained using classification …

Distinguishing Medial Temporal Lobe and Prefrontal Cortex Contributions to Approach-Avoidance Conflict in Healthy Controls and Generalized Anxiety Disorder: Insights from Functional Magnetic Resonance Imaging and the Hierarchical Drift Diffusion Model
… temporal lobe (MTL), striatum, and prefrontal cortex (PFC). This work, however, is limited in two respects. (1) Human models employing functional Magnetic Resonance Imaging (fMRI) have historically relied on analyses that fail to disentangle how neural activity relates to decision-making …

Potential for change: Characterizing synaptic plasticity following visual discrimination learning in adult rats.
… eye). The enhanced LTP in the primary visual cortex (V1) was blocked by an NR2B antagonist, suggesting that training resulted in changes in NMDA receptor expression or functioning. Next, the effectiveness of LTD stimulation protocols to elicit synaptic depression under in vivo conditions were …

Medial Temporal Lobe Structure and Function
… gyrus: PHG) and its subregions: entorhinal cortex, perirhinal cortex, and parahippocampal cortex: ERC, PRC and PHC. respectively). The subdivision of the PHG into its subregions was novel, and required the development of new methods for cortical assessment and parcelation. The specific aims …

From Face Perception to Individual Recognition: The Missing Link
… the temporal lobe. One area was located in the perirhinal cortex (PR), which has been associated with declarative memory, and the other area was embedded in the temporal pole (TP), a region previously associated with social knowledge. These two novel face areas showed a non-linear response as …

Adult behaviour and cerebral cell densities after maternal or post-weaning consumption of an obesogenic diet in mice
… by increased GFAP+ astrocyte density within the perirhinal cortex for HFHSC and CHFHS females. Overall, consumption of the HFHS diet post-weaning led to a larger range of adult behavioural changes and more robust alterations to cerebral cell densities than maternal consumption alone.
